Back

Pairs of valence electrons.

Front

NH₃ and BH₃ have the same shape. True or False?

Back

Front

What is the bond angle in a tetrahedral molecule?

Back

109.5 Degrees.

Trigonal planar.

Front

What is the effect of lone pairs on bond angles?

Back

Lone pairs repel more strongly than bonding pairs, reducing bond angles.
